Title: Redline on Tachometer?
Post by: 1968 on May 24, 2019, 02:19:08 AM
It seems that some tachometers have the redline and others do not.  Was it a mid-year change like the recessed rear quarter panel reflectors?  Was the redline only on later built cars?  (Maybe it was added mid-year to cut down on warranty repairs!)

Correct, some are redline, some are not.

I havent studied them to see if its date specific?

That's an unknown at this point. There were also some cars with 6,000 rpm tachs so maybe it is just a supply issue?

(FWIW this is the case on '67 Shelby's too, a year earlier and on the other coast - Ford Job #1?)

The 6K tach seems like a supply issue.

Given it was a issue seen in 67 Shelby's also leads one to believe it may not be date related.

FWIW, I looked at a bunch of photos, and the only pattern I saw was that all cars with knee pads had no redline on the tachs.  I believe that knee pads ran out in December 1967, so maybe the original plan was no redline.

My early 68 GT350 did not have the red line, original owner and the car was built in Nov 67.

Interesting.  I believe the knee pads ran out in December, so that must have been one of the last ones.  Maybe the no redline tachs ran out just a little before the knee pads?

Apparently you didn't read or are ignoring information from other reply's. To restate other reply's the redline no redline was apparently random in 67 which all had knee pads but the redline or no redline tach had no apparent pattern of usage in 67 . Both were used from the factory in 67. That seems to contradict a early late hypothesis .The somewhat no pattern usage seemed to have continued to be so in 68 also.

I did read and I am not ignoring those replies.  1968 was a completely different situation due to the strike and the change in GT Mustang tachs from 1967 to 1968.  Also, many tachs on restored cars have had the redline added by Shelby "experts" who believed the redline had faded away or the non-redline tach was incorrect, which of course is wrong, but which makes it more difficult to date a production change.  For 1968, it seems that a running production change was likely, with the earlier cars having no redline.

Help me understand how you think in what way that the strike effected the tachs . Help me understand what you perceive as the main difference between 67 and 68 tachs. Thank you in advance for explaining your point of view.

I suggest that you research 1967 and 1968 Mustang tachs and the GT option.  We still may have a difference of opinion, but that is fine.

I was not trying to have a difference of opinion but only trying to understand your point of view as it relates to the discussion. I thought I asked a straight forward non combative statement. If you don’t want to explain yourself after making a seeming out of context statements as it relates to the discussion without any back up then so be it. Maybe after you do YOUR research you will feel confident enough to answer my question so that we can continue the conversation.

FYI I would like to determine a pattern also if It exists, C7,C8 engineering number aside, maybe something as simple as two different vendors. Hopefully this discussion will help shed some light on the subject.

I would be interested to know how much the strike effected 1968 production of Shelbys.
